SUMMARY REPORT ON PERMANENT DEFORMATION IN ASPHALT CONCRETE
This report evaluates information on the permanent deformation characteristics of asphalt-aggregate mixtures, with an emphasis on laboratory test techniques for measuring mixture resistance to permanent deformation, and on methods for prediction of permanent deformation (rutting) in the upper asphalt bound layers of pavements. Factors influencing the amount of rutting are summarized. The laboratory test methds associated with the predictive methodologies that are evaluated include: unaixial and creep tests; uniaxial and triaxial and repeated load test; triaxial dynamic tests; diametral tests, creep and repeated load tests; hollow cylinder tests, combined axial and torsional loading; simple shear tests, unconfined and confined; and wheel-track tests. From these evaluations, specific test methodologies are ranked in order of preference.
